Abstract:

A large acceptance pair spectrometer to detect photons from the radiative muon capture (RMC) process was built. The spectrometer was used to measure the RMC branching ratio for AI, Si, Ca, Mo, Sn and Pb. Two recent theoretical models were used to extract the RMC branching ratio in Ca. The experin1ental result is in good agreement with the world average value, but yields a value for the pseudoscalar coupling constant, gp, which is lower than the Goldberger-Treiman PCAC prediction. In the absence of a theoretical model to predict the R11C rates for Al and 5i, only the branching ratios for

Abstract:

The proposed neutrino factory, a facility for precision measurements of neutrino oscillations, requires directional neutrino beams to reach the required sensitivities. Among the few sources of such beams is the decay of muons travelling at relativistic speeds, therefore an intense source of muons and subsequent rapid acceleration must be designed so they can reach the required energy before decaying. This thesis considers several stages in this process: pions are produced from a proton beam hitting a target and pion yield optima are determined as a function of target design parameters and the

Abstract:

The photon asymmetry (⍺⋎) and partial branching ratio (Rk>57), for radiative muon capture on ⁴⁰Ca, have been measured in order to determine the magnitude of the induced-pseudoscalar coupling constant, gp. A large Nal(Tl) crystal (46cm ϕ x 51cm) was used with an active Nal(Tl) converter (36cm x 30cm x 5cm) as the photon detector. The combined system had an energy resolution of 15% at 70 MeV; a factor of two improvement over previous similar experiments. Simultaneous measurements of the photon asymmetry and the partial branching ratio have been performed twice in the past. From a theoretical st

Abstract:

The partial branching ratio for photons of greater than 57 MeV (G[sub >57]) has been measured for radiative muon capture (RMC) on ¹²C, ¹⁶O and ⁴⁰Ca in order to determine the magnitude of the induced pseudoscalar coupling constant g[sub p] of the weak hadronic current. A time projection chamber (TPC) was used as a large solid-angle, medium-resolution pair spectrometer to detect the photons from RMC. The resulting spectra were essentially background-free, allowing a determination of the partial branching ratios to about 10% precision. For ⁴⁰Ca, the partial branching ratio obtained is in good ag

A photon asymmetry measurement in radiative muon capture (RMC) on ⁴⁰Ca has been carried out in order to determine a value for the induced-pseudoscalar coupling constant (ցƿ), thereby allowing us to investigate the possible renormalisation effect for this coupling constant inside nuclear matter. Negative muons from the M20A channel at TRIUMF were stopped in a ⁴⁰Ca target. The resulting RMC photons were then converted by a 5 cm thick Nal converter placed immediately in front of our main detector, a Nal crystal of size 46 cm∅x51 cm.

Negative muons produced via the backward decay of pions in the M9b beam channel at TRIUMF were stopped in a ²⁸Si target. The energies of the muonic X-rays and nuclear γ-rays following the muon capture were measured in order to identify a Doppler broadened γ ray line in ²⁸A1 which is suitable for analysis in terms of a γ — ν angular correlation to determine a value for the induced-pseudoscalar coupling constant (gp ).

Abstract:

In the last ten years, the Fe-based superconductors have been extensively investigated both from the experimental and theoretical point of view, and many studies have been devoted to investigate the intimate interplay between the magnetic and superconducting phases. However, many aspects of their phenomenology are still unclear. In this thesis work we focused onto a specific material family, namely the LaFeAsO1−xFx (1111), to perform a systematic experimental investigation of the superconducting and magnetic microscopic properties as a function of the Fluorine doping.

Abstract:

Translational energy spectroscopy is an invaluable tool in the study of ion-neutral processes. By measuring the change in energy of the projectile ion information can be obtained about the initial and final states of the projectile and the final states of the target (presuming that the target possesses only thermal energy and is initially in its ground state) for a wide range of collisional processes. One such process is that of electron capture where the multiply-charged ion will capture one or more electrons from the target. The Wigner spin-conservation rule has previously been studied for b

Abstract:

A sensitive search has been carried out for the rare decay $\rm K\sb{L}\to\mu e$. This decay violates conservation of separate lepton-number and thus is forbidden in the Standard Model of electro-weak interactions. Many new models have been proposed which could permit this process. The data were collected in the B5 beamline of the Alternating Gradient Synchrotron facility at the Brookhaven National Laboratory during the Spring, 1988 slow-extracted beam running period. The experiment was sensitive to approximately fifty million $\rm K\sb{L}\to\pi\pi$ decays. No $\rm K\sb{L}\to\mu e$ candidate e

An electron-ion time-of-flight coincidence technique was used to determind the ration of the K-K electron capture cross section, OECK, to the K-vacancy production cross section, oVK. These ratios were then combined with the measured values of oVK to extract the K-K electron capture cross sections. Measurements were also made for protons of the same energy range but with regard to L-shell vac

Abstract:

The purpose of this thesis is to study the electron spin relaxation (eSR) in small organic molecular semiconductors using the muon spin relaxation (MuSR) technique. One of the inherent problems in utilising the spin degree of freedom is the lack of understanding of the fundamental mechanisms behind spin relaxation. Two interactions have been proposed as the dominant mechanisms behind the spin relaxation, the Hyper ne interaction (HFI) and the Spin Orbit (SO) interaction. There remains much debate over the models for these interactions and their exact role, a contention that drives the work car

Abstract:

The ATLAS experiment is used to observe the √s=7 TeV proton-proton collisions produced by the LHC at CERN. This gives an unprecedented opportunity to search for physics beyond the Standard Model at hitherto unexplored kinematic regimes. Supersymmetry (SUSY) provides interesting solutions to a variety of theoretical problems that may be encountered in the Standard Model at high energy scales, while providing signatures that may be observed at the LHC. However, in order to produce a search that is sensitive to SUSY it is vital to understand how the physics that has been discovered to date may pr

Abstract:

Electron capture supernovae (EC-SNe) are the deaths of approximately 8-10M stars. In this thesis, the evolution of 8-12M stars is calculated using the MESA stellar evolution code. The aims of this thesis are to produce the most advanced and up-to-date progenitor models for electron capture supernovae (EC-SNe) and to study the behaviour of stars across the transition mass range between AGB stars and massive stars. These new stellar models will be the first of their kind since the 1980s and highlight new computational successes and persisting challenges in the field of stellar physics.

Abstract:

A search is presented for a high mass neutral particle that decays directly to the e(+/-) mu(-/+) final state. The data sample was recorded by the ATLAS detector in root s = 7 TeV pp collisions at the LHC from March to June 2011 and corresponds to an integrated luminosity of 1.07 fb(-1). The data are found to be consistent with the Standard Model background. The high e(+/-) mu(-/+) mass region is used to set 95% confidence level upper limits on the production of two possible new physics processes: tau sneutrinos in an R-parity violating supersymmetric model and Z'-like vector bosons in a lepto

Abstract:

The hunt for Dark Matter plays a truly critical role in contemporary physics. At both the largest and smallest scales, deep questions are being raised about the fundamental nature of the universe - questions that confirmation and then characterisation of particle dark matter will provide many answers to. This thesis presents some of the world's most sensitive searches to date for certain types of axion dark matter, axion-like particles, and two-neutrino double electron capture. These have been conducted using the Large Underground Xenon (LUX) experiment. Evidence for dark matter and physics be

Abstract:

The COherent Muon to Electron Transition (COMET) experiment will be searching for the charged lepton flavour violating process µ _ + N(Z, A) -+ e_ + N(Z, A) in aluminium with a single event sensitivity of 3 × 10_17. In order to achieve this sensitivity, COmet will utilise a novel pion capture solenoid and a high power proton beam to create the most intense pulsed muon beam in the world. Because these are innovative technologies, it is not known exactly what the muon yield will be and so, in this thesis, simulations of this section of the experiment have been performed using a variety of hadron
